Allergic rhinitis (AR) is a global health problem because of its steadily increasing incidence and prevalence that currently concerns about 30% of the world’s population. Although AR is not a disease that reduces the life expectancy, it is a disorder with a major impact on the quality of life of patients, resulting from an impaired social life, school performance and work productivity. Furthermore, AR produces significant costs for its treatment.
